Description

Elevator hauler wire rope protective structure Technical Field The utility model relates to the technical field of elevators, in particular to a steel wire rope protection structure of an elevator traction machine. Background Elevator hoisting machines are key devices in elevator systems for driving a car up and down. The rotary motion of the motor is converted into the vertical motion of the car through the friction force of the steel wire rope and the traction sheave. The hoisting machine is usually mounted on top of the elevator shaft and is the core component of the elevator operation. The protective cover is arranged between the traction wheel and the guide wheel, so that the steel wire rope can be protected, and the steel wire rope is prevented from being influenced by external environment. The Chinese patent with the bulletin number of CN212953740U discloses an elevator with a telescopic protective cover, which comprises an elevator carriage body, wherein a traction machine and a machine room guide wheel are arranged above the elevator carriage body, a steel wire rope sequentially bypasses the traction machine and the machine room guide wheel, the protective cover is arranged on the steel wire rope between the traction machine and the machine room guide wheel and comprises an upper protective cover and a lower protective cover which are mutually sleeved, a chute is formed in the overlapped part of the upper protective cover and the lower protective cover, a locking bolt is connected in the chute in a sliding manner, the traction machine is arranged on a spandrel girder through a traction machine base, and the protective cover is fixedly connected on the traction machine base through a protective cover fixing plate.
